+Add a source-free installation regression for #8907, the macOS arm64
+v0.5.1220 `node:http` link failure previously fixed by #5983. Exercise the
+full prebuilt runtime, stdlib, and HTTP wrapper in both default and
+`PERRY_NO_AUTO_OPTIMIZE=1` modes, checking that the minimal server links,
+listens on an ephemeral port, closes, and exits successfully.

+//! #8907: the v0.5.1220 macOS arm64 release could not link node:http.
+//!
+//! #5983 removed the external HTTP pump from the full stdlib. The #8587
+//! feature-graph guard protects that fix, but does not exercise the linker.
+//! Stage a source-free installation with the full archives and compile the
+//! reported server in both default and PERRY_NO_AUTO_OPTIMIZE modes. This
+//! must work without a source checkout repairing the libraries via auto-opt.
+
+// The macOS/Linux CLI is self-contained. Windows additionally needs LLVM-C.dll
+// staged beside the executable, which this Unix installation regression omits.
